Right. And I think it's often misunderstood that these parts don't actually need to have been under strict, detailed co-ordination to work, because the whole thing just needs to be set in motion when you have teams of people who can react on the ground.

But some people had advance plans to create pressure in the knowledge that it might lead to disorder, and then exploit the uncertainty in the moment. It could really all have happened, and it hinges on small moments of bravery that are well documented now but that many of those involved seem hesitant to admit to in public, which shows you that the landscape of threat still exists.
